WARPING-MACHINE;

Toul@ inkom tim/dy concer/t.'

Be itknown that LABRA' VAN Hasse, a

citizen of thel United States, residing at andy useful improvements in Warping-Machines, of which the following is a specification. .A n f,

This invention relates to warping ma-V chines, and particularly to so-calledSwiss warping machines, in which the warp is laid on the reel ina succession of bands or sections wound thereon spirally, ythe motion toppro-l saidcarriage and yet permitting it to be reset Y duce they spiral winding being effected byI` traversing the reed carriage laterally while the reel is rotating. My invention consists in a novel means for eifecting the traverse of the to a newstarting point whenever the winding-on` of one section is completed and that ofanother isto begin. My inventionfurther consists in a novel means for gaging the resetting position of the carriage, so that each section may be depositedon the reel in precisely thelsame spacing from a previously wound section as any other two sections.

In the accompanying drawing,y

Figure l is a side elevation ofV a 'warping machine carriage provided with Amy im.v proveinents, the guide-barsy on whichit travels and its traversing screw appearing; in;

section;

Fig. 2 is a fragmentary plan' of kwhat is shown in Fig. 1, apartof the carriage appearing broken away; and

Fig. 3 is a front elevatiomnshowing the carriage in vertical section on line 3-3 of Fig. l. On a guideway formed by the usual pair :of guide-rods@ is arranged to slide theca-r-l riage provided with the usual warp-guiding rollers c and reed d. e is the usual suitably rotated screw whereby the traverse is,`

imparted to the carriage.

vIn cross-walls of the carriage (designated a) is journaled a front-to-rear extending arbor f ony which is fixed a worm-wheel g, the arbor being kept from longitudinal shifting by the contact of said wormwheel and a collar 7L with the cross-walls, as shownin jsetinav l `VSpecification of Letters Patent.v Patented 001]'e 30, 1917.' appiication flied aprilia, i917. r`s,@nai-iv'0.162,868. i y

y the-.'arbor when thethumbvscrewfis screwed down. When the` plug .ismade to bind worm-wheel, isA held fromturning,y the Acarriagewill be traversed byl thev rotating screw or worm e, and when the plug` is released the.y I

carriage .may be shifted by hand.independ-L ently ofwthescrew or worm, the arbor7 then turning with they wormwheel in its bear-y ings Mv;Constr-uctolftthus. to Obtain a diS- connective connection between the carriage and thefwormor screw, iseXtremely simple,

and whilea reliable connection between thev worm and. carriagemayjbe had, the connectiony may be established or disestablished with Vthe greatest facility and convenience.

In vsection warping, theL start ofy the, lay

ing-on of each new section should begingalv definitev distance 'to' one sideof the start of the preceding VAsection 5x suchv distanceisusually that betweenganyl two threads in a section, and the-,startingkpoint ofn each new section isr usually onthat side of thestarting point ofthe precedingsection .OPPOSite to that from which the traverse pi'oceedsf, I

in other words, if the traverse isfrmlleft toright,- the resetting of the carriage (fromy right kto left) is such that lits y'new starting point is to the left of its, preceding starting point. My meansfor determining'eachfnew,v startingppoint with precision isy designed to facilitate the gaging and insure againstl mistakes f being made through y carelessness or visual'errors: .On the front rod a I place a collar Zlprovidedwith a set-screw mffor,

clamping it at any point on the rod.r On a screw n inthe adjoining. side k of the .carriage an arm o is pivoted, and in the arm, penef. trating thesame, is arranged a barpwhicli may 4be shifted infthe yarm. longitudinally v (such bar being parallel with the guideway formed biyrods a) .and be held at `any point to which itfisfthus shifted by a set-screw g tapped. into the arm. The bar penetratesaholle r in the side ofthe carriage, such hole being largefenough to permit limited move-` ment ofthe arm on its pivot. The arm may restonthe guiderod when ythe carriage is spacedf from the collar Z not less than the distance indicated by Fig. 3; if the arm is raised and the carriage or collar moved one toward the other the arm will be supported by bar p resting on the collar. At s and t the gage member formed by the parts o-y), which is thus in effect stepped, affords face s of the arm, and there fixed by means of set-sorer g. Before starting to wind the first section, the collar/#Z is aiiixed to the guide rod a so that it abut-s the contact face At of the gage member. The first sec# tion is then wound. l/Vhen the winding-y on of the irst section has been completed,

the carriage (having released arbor f and the worm-wheel) is shifted back by handto the left-until the contact face s comes to bear against thel collar, the gage member being swung up on itsk pivot to permit this. The carriage will now be at the proper position for starting to wind the second sec-r tion. Before the'second section is `started to be wound, however, the collar is released and moved to the left and re-secured to the guide-rod-in such position that it abuts the contact face t of the gage member. These operations are repeated on the winding of each section.

' The hole 1" is made large enough only to permit the gage member to be raised sulficiently to permit bar p and not the arm to override the collar, thus to vavoid possible errors in gaging. But I donot wish to be restricted to this detail; for, while itis preferred to use the gage so that on the gaging movement of the parts involving the bar 29 overriding the collar Z the gaging contact shallv be as between the collar and the face s of the arm, rather than as between the collar and the side'of the carriage, this is not essential in the broad aspect ofthe invention. 1

It will be understood that the bar is adjusted longitudinally of itself in the 'arm` so that more or less thereof will protrude therefrom toward the collar, according to the width of the sections. In the example given, the section width being two inches, the bar is adjusted so thatits end t is two inches from the face s of the arm. f

Having thus fullyl described my invention, what I claim and desire to secure by Letters Patent is:

l. In a warping machine, the combination of a guideway, a carriage member movable along 'the guideway, means totraverse the carriage, an abutment member settable at stages along the guideway, and a gage aromvement against the other member.

2. In a warping machine, the combinationy of a guideway, a vcarriage member movable along the guide\vay,vmeans to traverse the carriage member, an y abutment V` member settable at stages along the guideway, and a gage includingtwo parts, one arranged in one member and the other laterally adjustable in the first-named part and said parts having lateral stepped faces to impinge the other member, Vsaid gage being movable in the member carrying it transversely of the guideway to present'either of said faces for impingement against the other member.

3. In a warping machine, the combination of a guideway, a carriage movable along the guideway, means to traverse the carriage, an abutment member "settable at stages along the guideway, and ay gage arranged inr one of said members and having a lateral' face to impinge against the other member, said gage being movable in the member carrying it transversely ofl the guideway to bring said face out of position to impinge theothermemberon movement of one of said members toward the other.

4. In a warping machine, the combination of a guideway member, a carriage member movable along the guideway member, means to traverse the. carriage member, an abutment member settable at stages along the guideway member, and a gage carried by one of 'said members and interposed betweenvthe carriage land abutment members and? movable to clear one of them trans# versely of the guideway member.

5. In afwarping machine, thecombination of a guideway member, a carriage member movable along the guideway member, means to traverse the carriage member,y an abutment member 'settable at stages along the guideway member, and a gage carried by one of said membersV and interposed between the carriage and abutment membersk and movable to clear one of them trans` versely of the guideway member, said gagev including tWo parts, one carrying the other and the latter laterally adjustable in the first-named part. y' n In testimony whereof I afhxmy signature.`
